Abstract: A part mounting device including a fixing metal member which is, in the inside of a synthetic-resin member, fixed to the other periphery of a metal member by the clamping force of a clamp screw. Inward protrusions are integrally formed on the synthetic-resin member, protruding radially inward. Engagement holes are formed in the fixing metal member for receiving the inward projections fitted into and engaged with the engagement holes. A bore is formed in the synthetic-resin member for inserting the clamp screw into the inside of the synthetic resin member.

Abstract: Disclosed is an internal combustion engine driven device having a knob which is operationally linked with a choke valve and is adapted to move the choke valve from the open position to the closed one. Provided on this knob are a movable contact including a contact section formed thereon, and a push-button switch for bringing this movable contact into contact with stationary contacts so as to supply the starter motor with electricity.

Abstract: A starting system for an internal combustion engine wherein an output shaft of a reduction device of an automatic starter is arranged into and passing through an axial bore formed in a boss portion supporting a recoil drum of a recoil-type manual starter, and a second connecting member of a clutch device is arranged on the output shaft in such a manner that the second connecting member can be shifted axially to engage or disengage with respect to a first connecting member of the clutch device.
